Crank shaft play?
Just started to tear down my 454 I just got last week. I pulled out the pistons and just wanted to clean everything up and put it together for this season untill I build the motor up in the winter. Anyway, I pulled the pistons and noticed that the crank shaft has play in it. By play I mean it can move in the length about 1/16" of an inch. I'm not sure if this is common for a crank to do this or not so I thought I would post it and ask.
As for my plans for the rest of the motor....I have an extra 366BBC and I am going to use its heads which are marked HI-PERF and have large oval intake ports and small valves which are good for low end torque. The heads also have 108CC combustion chambers instead of the 118CC like the 454 has. What I am going to do is get the heads shaved to lower the compression even more with the flat top pistons so I can run racing gas or alky.
